The slope of any line perpendicular segment AB to where A(0, -3) and B(4, 9) are two points on the line, is m =

-3

-1/3

3

Answer 1

product of slope of perpendicular line=-1

Answer 2

so -3?

Answer 3

sorry, i dont understand

Answer 4

what is the slope of AB??

Answer 5

@emok9893

Answer 6

i dont know what the formula is

Answer 7

u know how to find slope ??

Answer 8

no

Answer 9

\[slope =\frac{ y2 -y1}{ x2-x1}\]

Answer 10

take one point as (x1,y1) and second as (x2,y2)

Answer 11

how to do?

Answer 12

im confused on how to set up the equation

Answer 13

\[\frac{ 9-(-3) }{ 4-0 }=??\]

Answer 14

that equals 3

Answer 15

take one point as (x2,y2) let (4,9) is
so x2=4
y2=9

Answer 16

yeah now slope of perpendicular = -1 /slope of the line

Answer 17

-1/3

Answer 18

thanks

Answer 19

welcome:)
